Let's begin.

VERDICT: NEEDS_IMPROVEMENT

Implement Min Stack (MinStack.java)

Your solution is well-implemented and correctly solves the problem. Here are some points to consider for improvement:

1. Data Types: The problem constraints state that values are integers, so using int in the Pair class is sufficient. Using long might be unnecessary and could lead to confusion.
2. Code Structure: For LeetCode submissions, it's best to include only the required class (MinStack) without additional classes or main methods. The test code and MyHashSet class should be removed to avoid confusion and ensure the solution is focused.
3. Error Handling: The problem states that operations will always be called on non-empty stacks, so the error handling (throwing exceptions) is not strictly necessary. However, it's good practice to handle edge cases, but you can rely on the problem constraints to simplify the code.
4. Efficiency: The solution is efficient, but you can consider initializing the stack with a capacity if you know the maximum number of operations (though not required here).

Overall, your approach is solid and demonstrates a good understanding of the problem. Keep up the good work!
